A lot of variables here. Was the boiler servicing the heating zones durring part of the test? What do yo mean by "cold start"? Was the boiler starting at room temp? How cool did you let the Phase III get to before turning the boiler on? Sounds like you let it get much cooler then 120°. Normally the Phase III would call for heat after it drops 5-10 degrees from set temp.
Now that you are are on low fire, does the boiler still short cycle and or make noise? Does it seem that you have plenty of hot water even when the heating zones are running?
